Gulf Oil Producers Seek Massive Crude Storage Expansion in Japan and South Korea

Expanding Gulf Crude Stockpiles in East Asia
Saudi Arabia and the United Arab Emirates are negotiating with the governments of Japan and South Korea to increase their on-shore crude oil reserves. Each exporter currently stores roughly eight million barrels in Japanese tanks; the talks aim to raise those volumes by as much as ten-fold. The discussions are private, and the parties have asked that details of the final storage amounts and cost-sharing arrangements remain confidential.
Drivers Behind the Shift
The push follows a prolonged disruption of maritime routes that carry Middle Eastern crude. Houthi attacks in the Red Sea have repeatedly halted shipments through the Bab el-Mandeb Strait, while the Strait of Hormuz remains effectively blocked, limiting the flow of oil through the world’s most critical chokepoint. Both Saudi and Emirati producers operate overland pipelines that bypass Hormuz, but those routes can only carry limited volumes. Storing crude in East Asia would allow the Gulf exporters to continue supplying their largest Asian customers even if sea lanes stay compromised.
Scale of Proposed Storage
- Current Japanese holdings: ~8 million barrels each for Saudi Arabia and the UAE (Kuwait holds ~3 million barrels).
- Requested expansion: up to ten times the existing volumes, potentially exceeding Japan’s available tank capacity.
- Parallel talks are under way with South Korea on similar reserve expansions.
Official Negotiations and Responses
Japanese authorities acknowledge the strategic benefit of larger foreign crude reserves but note that allocating more tank space to overseas producers would reduce capacity for domestic refiners’ commercial inventories and the nation’s strategic petroleum reserves. Both governments indicate that talks are ongoing regarding the precise scale of storage and the division of associated costs.
Implications for Regional Energy Security
For Japan and South Korea, securing extra Middle Eastern crude on their own soil would hedge against future interruptions in global shipping lanes, enhancing energy stability for the world’s largest oil-importing economies. Conversely, the shift could strain domestic storage resources, forcing refiners to adjust inventory strategies. The outcome of these negotiations will shape how the Asian market manages supply risk amid continued volatility in the Persian Gulf region.
